Choosing between c’est and il est requires learning a few specific rules.

Both phrases translate to “it is” in English.

However, French grammar dictates very specific situations where you must use one over the other.

Using the correct phrase ensures you sound natural to native speakers.

Fortunately, the rules for telling them apart are highly logical and easy to memorize.

I’ll break down exactly when to use c’est and when to use il est below.

The basic translation of c’est and il est

The expression c’est combines the demonstrative pronoun ce (this/that/it) and the verb est (is).

It literally means “this is”, “that is”, or “it is”.

The phrase il est combines the personal pronoun il (he/it) with the verb est (is).

It literally translates to “he is” or “it is”.

The feminine equivalent of il est is elle est (she is / it is).

Because both c’est and il est can mean “it is”, English speakers often mix them up.

You just need to look at the words that come immediately after the phrase to know which one to choose.

When to use c’est in French

You must use c’est when introducing a person, a thing, or an idea.

Here are the exact grammatical rules for using c’est.

With a modified noun

A modified noun is any noun preceded by an article (un, une, le, la) or a possessive adjective (mon, ton, son).

If you have a determiner before the noun, you must use c’est.

With proper names

Whenever you state someone’s specific name, you must use c’est.

You can’t use il est or elle est before a proper name.

With stress pronouns

Stress pronouns include words like moi (me), toi (you), lui (him), and elle (her).

When identifying who someone is, use c’est followed by the stress pronoun.

To describe general situations or opinions

Use c’est followed by a masculine singular adjective to make a general statement or give an opinion about a situation.

Don’t use this to describe a specific object or person.

When to use il est in French

You must use il est (or elle est) when describing a specific person or object that has already been introduced.

Here are the specific rules for using il est.

With an unmodified noun for professions, nationalities, or religions

An unmodified noun has no article (un, le, etc.) in front of it.

In French, professions, nationalities, and religions act like adjectives when describing someone.

You must use il est or elle est in these cases.

Notice that there’s no un or une in the French sentences above.

If you add an article to describe the person further, the rule switches back to c’est.

With adjectives describing specific things or people

When you describe a specific person or a specific item, use il est or elle est.

The adjective must agree in gender and number with the noun you’re describing.

When telling the time

There’s no debate when it comes to the clock.

You must always use il est to express the time of day.

Plural forms: ce sont and ils sont

The exact same rules apply when talking about multiple people or things.

The plural form of c’est is ce sont (these are / those are).

The plural form of il est is ils sont (they are).

For feminine groups, you’ll use elles sont (they are).

If you’re pointing out your friends (modified noun), use ce sont.

If you’re describing their nationality (unmodified noun), use ils sont.
